Lightest gaming mouse

Lighter mice are easier to flick and less tiring over long sessions — which is why the featherweight class has taken over competitive FPS. Below the catalog ranked purely by weight. Note the honest caveat: under ~60 g the differences are about feel, not measurable aim gains, so don't chase grams past the point your hand is comfortable.

How we ranked these

Ranked strictly by sourced weight in grams, lightest first. No editorializing — it's a measured spec.

The picks

Ranked strictly by weight. Each pick's measured build score is shown as context — every one already clears the competitive floor, so it's bonus engineering, not a win-rate order. Pro adoption is shown for context too; it never moves the ranking (the most-used gear page ranks by that).
